For small angle the large downward force at the wall contact point and the large upward force at the diagonal rod point both go to...

As far as the jig is massless rigid body, the essential lengths are 0.28 m and 0.16 cot 55 m. The diagonal rod triangle is to give...

The touch of theta diagonal rod to the horizontal rod generate theta force whose horizontal component decides magnitude of F. Is it...

In survey of "the only horizontal bar" model, I would like to know how we should choose the shape of the pivot in this figure to...

My bad! So we have same F.

Your equation ##~L_2w=hF_x~## in #16 gives $$F_x=\frac{L_2}{h}W.$$ If you cast it in terms of the given quantities, namely ##L_1## (0.16...

My answer #16 which is same as the exam answer has sec, however post #13 answer has tan as coefficient to $$W\frac{L_2}{L_1}$$.

The blue length is important. The angle itself does not matter. Alternative orange rods are OK. The diagonal rod tansmit not only force...

No, not the same in a exact sense. My post #16 based on your figure deals it. Your case can be interpreted that we pull the horizontal...

|D|,|F| > |W|. The weight gravity generates larger y force. F is downward, however red force on screw is upward.”Only horizontal...

I mean couple not moment. Thanks to #6 in usual case Blue forces couple and red forces couple cancel. My #16 confirms it. In the...

Is the net couple zero in this system? The couple produced by the two forces in the x-direction is zero. However, it seems that the...

In your examples the connections must transmit a torque. In the solution given by @kuruman they are assumed to be torque free. Based on...

Thanks. My thread examples were not appropriate. Net zero inhomogeneous x force act at the contact area of the remaining bar so that it...

$$F_y=w-D_y$$ it can be negative, zero or positive. Some example cases $$F_y=w > 0,\ \ D_y=0$$ $$F_y=0,\ \ D_y=w$$ $$F_y<0,\ \...
